Hi Daniel, unfortunately that's not a great setup for planetary.
Firstly, your scope is too short in focal length, you will need to get up to f/20 or so for best results (so a 4/5x Barlow will be required). The optimum focal ratio for planetary is about 5x the pixel size of the camera.
Next, the Nikon series of cameras are not great for video imaging either, the Canon DSLR system works almost as well as a dedicated astro camera like the ASI224MC using the Liveview feature, but the Nikon system does not. Using the in camera video stream is not good either, the compression used to make the video screws up the frames and the image quality suffers.
This is how I started in planetary with my Canon 700D

If you really want to get into planetary, then you should probably look into a new camera like the ASI224MC or a second hand Canon on ebay.

Sorry for the bad news, but you might as well get it up front before spending a lot of time with equipment that is not well suited for the job.
